Whether it is true or not that not more than twelve persons in all the world are able to understand Einstein's Theory, it is nevertheless a fact that there is a constant demand for information about this much-debated topic of relativity. The books published on the subject are so technical that only a person trained in pure physics and higher mathematics is able to fully understand them. In order to make a popular explanation of this far-reaching theory available, the present book is publis...

Albert Einstein (14 March 1879 – 18 April 1955) was a German-born theoretical physicist who developed the general theory of relativity, one of the two pillars of modern physics (alongside quantum mechanics). While best known for his mass–energy equivalence formula E = mc2 (which has been dubbed "the world's most famous equation"), he received the 1921 Nobel Prize in Physics "for his services to theoretical physics, and especially for his discovery of the law of the photoelectric effect". T...

The Einstein Theory of Relativity usually encompasses two interrelated theories by Albert Einstein: special relativity and general relativity. Special relativity applies to elementary particles and their interactions, describing all their physical phenomena except gravity. General relativity explains the law of gravitation and its relation to other forces of nature. It applies to the cosmological and astrophysical realm, including astronomy. The theory transformed theoretical physics and a...

NEW YORK TIMES BESTSELLER • Thirteen extraordinary essays shed new light on the mystery of the universe—and on one of the most brilliant thinkers of our time.“[Hawking] sprinkles his explanations with a wry sense of humor and a keen awareness that the sciences today delve not only into the far reaches of the cosmos, but into the inner philosophical world as well.”—The New York Times Book ReviewIn his phenomenal bestseller ...

Relativity and Quantum Mechanics are the two major pillars of 20th century physics. These theories, launched within five years of one another, revolutionized our understanding of nature. They utterly dismantled the conceptual basis of Newtonian physics that had been the gold standard of science for over 200 years, and introduced radically new concepts that defy human intuition. These theories may represent the greatest upheaval in the history of science. Both Relativity and Quantum Mechani...

Magnetism is a strange force, mysteriously attracting one object to another apparently through empty space. It has been claimed as a great healer, with magnetic therapies being proposed over the centuries and still popular today. Why are its mysterious important to solve?In this Very Short Introduction, Stephen J. Blundell explains why. For centuries magnetism has been used for various exploits; through compasses it gave us navigation and through motors, generators, and turbines it has giv...

Our sun is an average star in our galaxy. It is a sphere of burning gas that provides light and heat. It makes our plants grow and allows them to turn carbon dioxide into breathable oxygen.If our sun were to shine a little less or a little more brightly, life as we knew it would not exist. A drop of less than 2% of the sun's energy output would turn Earth into an ice-covered planet.So how much do you know about this glowing sphere that controls our world. Can you answer these...

This book continues our exploration of the most profound theory of science, Einstein’s General Theory of Relativity.We examine more carefully the properties of spacetime, the unity of space and time.We explore the major features of curvature, how to measure it, and how to reduce its complexity to finding distances between nearby points.We find a simple expression, 2M/r, which proves remarkably helpful as we explore the Schwarzchild metric, black holes, time dilation...

With this book you begin exploring the mysterious world of Quantum Mechanics — two words that have for over 100 years struck terror in the hearts of both physics students and the general public.As we shall see, the behavior of nature is remarkably surprising in the micro-world of molecules, atoms, and everything smaller yet. But this should be a surprise of wonder instead of terror. For most of us, nature is also surprising on the savannahs of Serengeti, but who wouldn't delight in...
